Better get at least three so you have a parts supply. Few if any shops will service them.

Most of the time, canguy and I are in agreement but not this time. The Powerfist engines have proven to be quite successful for Princess, according to a contact I have at one store who isn't into BS'ing me about anything.

Secondly, you have the Princess guarantee to fall back on. If you are not happy for any reason, take it back and get a full refund.

As an example, I bought one of their air/hydraulic floor jacks and it developed a leak. When I took it back, I told them that I wanted another one instead of a refund. I was informed that head office pulled all existing stock off the floor because the failure rate of them was unacceptable. So, I had to take the refund and wait until they either got a new supplier or they tuned up the existing supplier regarding quality control.

I don't know what happened but when that style of jack became available again, I bought another one and haven't had any problems.

Another time, I bought a long handled ice chipper/scraper to use in our repair shop. Naturally, someone took it out of the shop and abused it. The wooden handle was broken off right where it enters the steel sleeve. I asked Princess if they had a replacement wood handle that I could buy and the answer was "No. Just bring in the broken one and we will either give you a new one or refund the original purchase price."

So... how do you go wrong dealing with a company that looks after its customers this way? My advice... go buy that engine and stop worrying.
